I noticed that it has an auto shutdown feature, if I leave the PC alone for a short period of time, maybe 20 - 30 minutes, then come back I find it shutted down. Even if I'm watching a film, and I use the keyboard to pause and resume it, but no mouse movement is done, after 20 to 30 minutes the 'first shutdown message' appears top layer, over the mplayer window. I have to close the shutdown window to stop it.

Is it possible to disable this feature, or to change the default shutdown timing to a longer interval?

I thought the /usr/local/pup_event/pup_event_frontend_d process was involved, but I killed it and the auto shutdown feature is still present.

Recently, I had a chance to review some of the Firefox problems recently encountered. Two problems stand out, and are sometimes used together.

The first is 'workers' that fetch data among other things. These have historically been a nuisance, but with the recent Meltdown/Spectre problems, their usefullness has ended on these older builds like FF27.

The second is 'indexed DB (database)', Again, its been a nuisance that is now in need of an off button.

So, about:config needs a few changes.

Disconnect from internet and open FF27.
In the address bar type about:config and be careful.
In the search bar type worker
Four entries will appear in FF27,
'FALSE' three of them, and change the numeric entry to 1.

OK, in the search bar type index
There will be numerous entries, but two of them are important right now...

dom.indexedDB.enabled
dom.indexedDB.experimental

Both of these two must be set to false (experimental 'should be' false by default)

Now that these are done, close the browser, wait 5-10 seconds and Goto MENU --> Shutdown --> Restart Graphical Server and click. (This step prevents a hang on normal re-starts of the browser).

Other things related to Meltdown/Spectre usually involve autocomplete, or autofill (because they involve caching predicted data). I have already (for a long time) mitigated these in about:config. Consider resetting them to false if you have enabled these 'conveniences'.

At this point, reconnect to internet as usual.

14.0 will have to be supported if for no other reason than Meltdown/Spectre. Right after the mozilla updates posted here, they also did a Thunderbird update (usually browser/T-Bird/ curl follow quickly). If I'm thinking correctly X11 will also get a major update (this is just my guess).
